Everspring is a farming sim that takes inspiration from the likes of Stardew Valley and Harvest Moon.
Every hour the lighting is updated/interped to have a day/night cycle. I had a problem where the directional light would do a 180* flip when interping from 12-1pm so at 12 I force the 180 flip without interp, which is why the lighting pauses for an hour at 11-12.
